MACHINE FOR REPRODUCING PHONOGRAPH-RECORDS.

SPECIFICATION forming part of Letters Patent No. 662,301, dated November 20, 1900.

Application filed March lfi, 1900. Serial No. 8,917. (No model.)

To atZZ whom it may concern:

Be it known that I, ADEMOR N. PETIT, a citizen of the United States, residing at New ark, in the county of Essex and State of New Jersey, have invented a new and useful Improvementin Machines for Reproducing Phonograph-Records, of which the following is a specification.

My present invention is designed as an improvement upon the device shown and described in my application for Letters Patent filed October 27, 1899, Serial No. 734,934, and which application was duly allowed February 24:, 1900.

The present invention is designed to make more effective the devices of my former application and to facilitate readily placing the .record and the blank on their respective cylinders and the after removal of the same.

In carrying out the present invention I employ a shaft for the record-cylinder and a shaft for the blanlecylinder and means for coupling together the said shafts; also, a support for the shaft for the blank-cylinderadapted for separating the respective shafts or uncoupling the same at pleasure. The shafts when coupled are in line and a followingstyle is in engagement with the record-cylinder and a reproducing-style is in engagement with the blank-cylinder. These parts are so supported and connected that the reproducing -style closely follows the movement of the following or tracing style, and the two move in unison, and in connection with these parts I employ adjustable devices for regulating the pressure or the weight ap- In connection with the sleeve for the blank-cylinder I employ an arm adapted to swing on the frame supporting the said sleeve, so as to permit the ready removal from the sleeve of the cylinder after the record has been made thereon.

In the drawings, Figure 1 is a plan view representing my present improvements. Fig. 2 is an end elevation of the same. Fig. 3 is an elevation and partial section of the arm and the supports for the recording and reproducing styles. Fig. 4 is a crosssection and partial elevation of part of the swinging frame carrying the sleeve for the blan k-cylinder and the movable arm at one end of the same. Fig. 5 is a broken sectional plan through the sleeve for the recording-cylinder and the sleeve for the blank-cylinder and their respective shafts; Fig. 6 is a partial plan and section representing a modification of the devices for support ing the sleeve for the blank-cylinder. Fig. 7 is an elevation; and Fig. 8, across-section and partial elevation representinga modified form of support and devices for operating the recording and reproducing styles, which is also the preferable form of apparatus. Figs. 3, 5, 6, 7, and 8 are of larger size than Figs. 1, 2, and 4 for clearness.

The shaft 0. is mounted in and supported by suitable bearings, and upon the said shaft at one end I place the fixed sleeve or carrier 1) for the record-cylinder, and 0 represents the sleeve or. carrier for the blank-cylinder.

d represents the record-cylinder, and e the blank cylinder. These cylinders are presumed to be of the same diameter and. to have parallel surfaces. They are, however, made with tapering inner surfaces to fit upon the tapering sleeves or carriers 5 c.

The back rod f is supported in any suitable manner and by a suitable frame or foundation, which also carries the bearings for the shaft a. The sleeve f surrounds the rodf' and is capable of a longitudinal movement thereon, and surrounding and clamped to the sleevef' is a sleeve 9, the setscrew for clamping the same being shown in Figs. land 2.

Movement is imparted to the sleevef by the usual screw-feed, (shown in Fig. 1,) but which being of ordinary character requires no further description. The sleeve 9 carries a curved arm g, extending over above the shaft or and the record-"cylinder d, and at the outer end of the arm g is an adjusting-bar It, held to the arm by a screw and bearing upon the rest-bar 2' below the same. The bar h occupies a slotted portion of the outer end of the arm g is provided with a socket receiving one end of the arm 70, which arm projects out from the said curved arm g and occupies a position transversely to the said arm and parallel with the shaft (1 and the cylinders. Upon this arm 76 are heads 34, that are adjustable and held in place by set-screws, (shown in Fig. 3,) and pivoted to these heads are the carrier-arms Z m, the carrierarm Z supporting the recordingstyle and being pivoted to the head 3 and the carrier-arm m supporting the reproducing-style and being pivoted to the head 4.

The recording-style n and the reproducingstyle 0 are each on the ends of bent arms n 0, pivoted between the parts of the carrier-arms Zand m at their lower ends. In Figs. 1, 2, and 3 the connecting-bar 8 is pivoted to the lower ends of the heads 3 and 4 and extends across from one headto the other, and the said bar is provided with a central finger 30 and short endfingers 34, andI provideaclip 28, in the form of a wire bent around the arm Zc,to frictionally engage the same, and a spring 29 is connected to the clip 28 at one end and i 5) and provided with a center, and I provide at the other end to the center finger 30 of the connecting-bar 8, and the fingers 34 at the ends of the bar 8 have links extendingtherefrom to the ends of the arms 71. and 0 of the recording and reproducing styles, and I pro- 3 of the frame 3, and this end of the shaft a is *pointed, and a spring-coupler 16 is secured thereto androtates therewith,the said springvide threaded bars 11 and 13, connected to and extending out from the carrier-arms Z and 'm, and upon said threaded bars 11 and 13 are the weights 12 and 14, adjustable along the said bars to bring the desired leverage and weight upon the styles, and I provide a-lsoa guide 1", verticallyadjustable and passing through a part of the carrier-arm m, the office of which is to rest upon the surface of the blank-cylinder e and following the same to give location to the reproducing-style 0 by following the contour of the surface of the blank-cylinder.

By reference to-Figs. 2 and 3 it will be seen that while the weight 14 tends to force downward the carrier-arm m toward the cylinder Z the spring 29, by its contractile action,tends to draw upward the finger to which it is attached and to turn the connecting-bar. 8 and in its action to raise the end fingers and links connecting the same to the arm 0 of the reproducing-style, the tendency being thus to press the style into the surface of the cylinder, while the action of the weight is to hold the carrier-arm down,with the surface of the guide 1 positively in contact with the surface of the cylinder. The action of the weight 12 upon the recording-style is somewhatsimilar,

because it bears down the carrier-arm Z and keeps the pointof the recording-style not only in the fine'groove upon the surface of the cylinder, but causes the same to follow all the In the modification and preferable form' shown in Figs. 7 and 8 the connecting-bar 8 extends across between the lower ends of the carrier-arms Z m, and the arms n 0 of the recording and reproducing styles are positively connected to this bar 8. In this form I also employ the clip 28 and the spring 29, with the lower end of the spring 29 connected to an arm 30, secured centrally of the connectingbar 8, the ends of the arms 72 and 0 being connected directly to the carrier-arms Z and m by springs 31 31,acting as a compensating- .spring between the carrier-arm and the arm it, according to the place at which the weight 12 is placed along the threaded bar 11, while the spring 29 acts,through the arm 30 and the connecting-bar 8, to force the styles against the surface of the record and blank cylinders.

Otherwise the structure of the parts carrying the recording and reprod uci ng styles are practically alike.

The end of the shaft a is tapered (see Fig.

an L-shaped frame 3, pivoted at s to a bracket of the main frame. The shaft a is centered at one end and reduced at the other end to pass through a short hub 35, made as a part coupler passing over the reduced end of the shaft a and the point of the shaft a passing into the center at the end of the shaft a, thus coupling the shafts a and a and causing them to aline.

Heads 0 frictionally surround the shaft athat is to say, these heads are provided with friction -hubs-and their peripheries screw into the ends of the sleeve 0, and they are adapted to be forced upon the shaft or, and I provide helical ring-springs 27, which surround the friction-hubs of the heads c,so as to insure the grippingaction of the same upon the shaft. The portion of the frame s-at right angles to the shafts Ct (1 sets over the rest-bar dot the frame, and a spring-actuated latch to, pivoted to the frame, is employed to engage this end of the-frame sand hold the same to the main frame of the machine, and the portion of the frame 8 that is parallel with the shaft a is reduced to form a stud end 15, that receives upon it the sleeve 25. held in .a fixed position by a setscrew 32, and the sleevetis notched along the back portion parallel with the stud end 15, (see Figs 1 and 4,) and the said sleevet is provided with a pin 20. Around the end of the stud 15 is received the hub of an arm t, the said arm being maintained in its relation to the said sleeve by a locking-screw .17 and washer, which screw 17 is received in a threaded opening in the end of the stud 15. A springpawl 18 and a pin 19 are connected to the hub of this arm 25, the pin 19 being adapted to come against the pin 20 to forma positive stop, bringing the axis of the arbor 21 into alinement with the shaft a, and the spring This sleeve Z is cease-1 pawl 18 is adapted to pass into thenotch in the back of the sleeve t to assist in determining this position, and it is also adapted to bear upon the surface of the sleeve to produce a friction capable of holding the arm t in an upright position and preventthe same falling during the removal of a record or the placing of a blank.

Through the hub t on the outer end of the arm 7., passes an arbor pointed at the left-hand end to pass into the center orsocket on the end of the shaft on to form a bearing for the outer end of the said shaft. This arbor 21 carries an arm 22 and a knurled head 23, and the same passes through a cam-sleeve 24, secured in the hub end 25 It will thus be seen that the arbor 21 can be rotated either by the fingers upon the knurled head 23 or by the fingers grasping the arm 22 and imparting a partial rotation to the arbor, which with the action of the can1-sleev,e 24 withdraws the point of the arbor 21 sufficiently from the end of the shaft a to permit the arm t to be swung out of the way of the sleeve 0 of the blank-cylinder and of the record or blank 6 thereon.

In the operation of the parts and after the record and blank cylinders are in place and the styles are set for the reproducing operation, the shaft or is rotated by any suitable means. I have shown in Fig. 1 a pulley at the left-hand end of the shaft for this purpose, and by the rotation of the shaft a and the operation of the usual screw-feed the sleeve 9, the curved arm g, and the styles and the devices supporting the sameare moved along over the surface of the record and blank cylinders for the purpose of reproduction, the record-cylinder d and blank-cylinder e being in the meantime rotated beneath the styles. When the record has been reproduced on the cylinder 6, the arbor 21 is turned and the arm t swung to one side to release the cylinder 6, which is removed from the sleeve 0. The latch it is then swung out of the way and the arm 5, with the shaft 0. and the sleeve 0, turns on the pivot 3' into and beyond the position shown by dotted lines, Fig. 1, simultaneously uncoupling the shafts a and a at the spring-coupler 16, so that access is given to the record-cylinderd forits removal, after which another record can be placed upon the sleeve b, the frame 8 and the parts he again coupled and connected, and another blankcylinder 6 be placed upon the sleeve 0, and the arbor 21 be again brought into posit-ion and the styles be placed to the starting-point for the reproduction of other records.

In the modification shown in Fig. 6 the part of the frame 5 parallel with the shaft a, together with the sleeve 1? and the arm t and the arbor 21, is dispensed with and instead thereof I provide a frame '1), also pivoted at s. to a bracket of the main frame, which frame is made with a tubular extension 22, through which passes the smaller portion of the shaft a and on the left-hand end of the said shaft, as shown in the drawings, is part of a clutch 26, engaging the other part of the clutch upon the shaft Ct.

The sleeve 0 is made slightly different in Fig. 6 from the structure shown in Fig. 5. In this form a head 25, with friction-fingers and a ring-spring 27, is employed, the sleeve 0 partially surrounding the shaft a and screwing upon the head 25. From this modification it will be seen that the blank-cylinder can be placed upon the sleeve 0 or removed therefrom at pleasure without the necessity of operating any mechanical devices, and that when it is desired to remove the record from the sleeve 1) the frameo is operated in alike manner with the frame 3. (Shown in Fig. 1.)

The recording-style n and its arm 01' (see Figs. 7 and 8) are preferably secured to the connecting-bar 8 by a pin 33, so that the parts tnrn together axially of the bar 8; but between the parts there is a looseness that permits of a slight lateral swinging movement of the arm n in relation to the bar 8 to provide for slight inequalities in the necessary movement of the recording-style n.
